About restoring individual files
If the option was enabled, you can restore the files and folders that existed on that virtual machine at the time of the backup.
If the option was not enabled, you can restore the full virtual machine only.
See Restoring the full Hyper-V virtual machine.
More information is available on the Hyper-V backup options.
See Creating a Hyper-V policy.
You can set up a configuration to restore individual files in any of the following ways:
Install a NetBackup client on another computer. Create a share on the virtual machine to allow that computer to access the virtual machine. (The virtual machine does not require a NetBackup client.) Specify the UNC path as the destination for the restore. More information is available on this option:
See Restoring individual Hyper-V files to a shared location on the virtual machine.
See Setting up NetBackup Client Service for restore to a shared location on the virtual machine.
Install a NetBackup client on the virtual machine where you want to restore the files. Restore the files to the virtual machine in the same manner as restoring to any NetBackup client.
See Restoring individual Hyper-V files to a host that has a NetBackup client.
Install a NetBackup client on another computer. Restore the files to that computer and then copy the files to the virtual machine.
To restore encrypted files, you must install a NetBackup client on the virtual machine and restore the files directly to the virtual machine.
See Restoring individual Hyper-V files to a host that has a NetBackup client.
You can use the NetBackup Backup, Archive, and Restore interface to restore files and folders from NetBackup for Hyper-V backups. NetBackup administrators can use the NetBackup web UI to perform server-directed restores of Hyper-V policy backups.
Important notes on Hyper-V restore are also available.
